LOCOMOTIVE-TENDER CISTERN.

i ,oesm c.

To all whom it may concern Be it known that I, Annnnw M. 'lvlcGinn,

of Sayre, in the county of Bradford, and;

frame of the tender; that it shall b6 pO-S* sible to stop most of its leaks without unloading the coal; and that it shall be capable of construction without the use of angle irons at most of the joints betweemits plates. And to such ends my invention consists in the locomotive tender cistern hereinafter specified.

In the drawings Figure 1 is a plan view partially in section of a locomotive tender cistern embodying my invention; Fig. 2 is a vertical longitudinal sect1onal view of hig. '1 on" a line 22; Fig. 3 is a half end elevation; Fig. 4 is a half front elevation; Fig. is a section ofFig. 1 on a line 5-5; Fig. 6 is ,a partial sectional view on the line6-6 of Fig. 1; and Fig; 7 is a detail showing the connection of a brace with the bottom plates.

My invention is capable of embodiment in manydifferent forms, and I have chosen the embodiment shown in the drawings as the best illustration of the principle of my invention known to me. Such embodiment, however, is to be regarded as typical only of many possible embodiments,

The general shape of my cistern-is that common to locomotive cisterns. It consists, when looked 'at in plan view, of a substantially U-shaped cistern, consisting of a tank 1, having legsEZ which extend forward, as shown in Fig. l, which inclose between them a coal space 3. The bottom 4 of the rear portion of the coal space is inclined, as

shown in'Fig. 2, so as to cause the coal to tend to flow to the front end of the tender,

and the space 5 beneath said bottom is utilized forwater The coal also lies upon the tops of the legs 2,. and for this purpose the Specification of Letters Patent.

upper plates 6 of the saidlegs are inclined inward and downwardly, as shown in Fig. 4-. The coal space is increased in height: by side walls '7 and a back wall 8 rising above the cistern proper, and by a front wall t), which open below so that. accessmay be had to the coal. A manhole i0 is provided to permit a man entering the cistern proper for the purpose of repairs and cleaning. So much ofthe'construction shown in. the drawings is old.

In practice, locomotive tender cisterns occasionally leak, and chiefly in the bottom seams of the cistern. Prior to my invention, in order to repair such looks it has been necessary to empty the tender of water and coal and to raise the cistern off the frame of the tender in order to get access to the joints between the plates and the rivets holding the plates together. This operation not only causes expense to perform the operation itself, but it takes a considerable amount of time during which the use not only of the tender but of the loco motive is lost.

By my invention it is unnecessary to lift the cistern off the tender frame in order to get at the oints and rivets even of the bot .tom plates,- and for some repairs it is even unnecessaryto unload the coal. 'lo accomplish this object I construct the cistern in the following manner; The bottom, forward of the tank 1, consists of a plate orplates ll, the width .of the coal space and plates 12 the width of the legs 2. To these plates are to be secured the outside plates 13 and the inside plates Ll of the water legs) I turn upward the edges 11 and 19 of the plates 11 and '12 respectively, and fasten the said plates to each other and to the vertical plates 13 and 14 by rivets 15, ivhich are thus made tostand horizontal. Both ends of the rivets are thus accessible for repairing, neither end of the rivets being beneath the plates ll or 12. ()wing to this construction it is possible to tighten the rivets or replace them without lifting the cistern off the tender frame. Moreover, the joints between the plates are exposed so that they can be callced from above. Further, the use of angle-irons as heretofore, to connect the vcrt l plates with the bottom plates also a. dad, thus saving expense, eliminatingone joint for each angle-iron, and eliminating one row of I rivets for-each joint.

Braces 16 and 1? connect thea'nclined bottom elof the coal space with the bottom plates 1.1, and "12 of the cistern. At theirlower ends, as shown inllig. 7, they are riveted tothe upturned edges or flanges of the i plates 11 and 12, so'that the rivets 15 are also horizontal and can be readily gotten at within the cistern Without requiring the cistern to'be lifted ofl' the frame of the tender.- As shown in Fig. 5, the joints between the inclined bottom plateslfof the coal space. and the adjacent top plate 6 of the water legs.

is formed by turning the edges or flanges l and 6, respectively, of these plates down Ward, so that they can be united by horizon, tal rivets l5 and the outer edges of the plate 6 'are also turned or flanged downward Where they are united to the side plates 13. As the plates 4 and 6 are normally covered with coal,'the construction just'describ'ed enables leaks -in the joints between these plates to be stopped by working Within the cistern, and thus the necessity for unloading thecoal for leaks at this point is avoided. i

It will beseen that every joint of mycis am can be repaired without raising the y cistern oil the tender frame, and-that most of the joints which are liable to leak can be reached without unloading the coal. 4

I claim:

1. In a locomotive tender, the combination vofa cistern and a frame upon which thecis-I ternis mounted, said cistern comprisingbottom plates having upturned flanges formed thereon, said flanges being united by horizontal rivets. I

In alocomotivetender, the combination of a cistern and a frame upon which the cistern is mounted, said cistern having bottom plates secured t0g8l'l101,tl1 joints of said bottom plates being united by horizontal riv v ets located above the bottom plates proper.

3. In a locomotive-tender, the combination of aeistern and a frame upon Which the cistern is mounted, said cistern comprising bottom plates having upturned flanges formed thereon, vertical plates, and horizontal rivets uniting said flanges and plates.

4, In a, locomotive tender, the combination of a cistern and a frame upon which the cis* tern is mounted, saidcistern having compartmentsboth for coal and water, thepartition between said compartments being composed of plates-having flanges formed thereon, saidflangespro ecting toward the Water,
